Identify the specific independent and dependent variables that will be involved in an experiment to test this hypothesis.. . List at least five variables that should be controlled during the experiment. For each variable identified, give a specific suggestion for how it can be controlled during the experiment.

The peripheral nervous system is involved in _____.
drek231 [11]

The peripheral nervous system is involved in both <u>voluntary and involuntary actions.</u>

Explanation:

The peripheral nervous system (PNS) is the neural system that resides outside the central nervous system (CNS). This contains nerves which in turn connect with the organs of the body like the sensory organs, glands, blood vessels, muscles etc with the central nervous system (CNS).

The PNS is divided into somatic and autonomic nervous systems.

The somatic nervous system contains sensory and motor nerve fibers which send sensory information and controls motor functions respectively. The voluntary movements of skin, skeletal muscles, bones, and joints are controlled by somatic PNS.

The autonomic nervous system composed of sympathetic, parasympathetic and enteric nervous systems controls the involuntary actions of smooth muscles of the internal visceral organs.

What do you mean by fermentation?

The metabolic process of fermentation alters the chemical composition of organic substrates through the action of enzymes. The process of generating energy from carbohydrates without the presence of oxygen is expressly stated as such in biochemistry. If the action of microbes produces the intended alteration to a food or beverage, it may more broadly refer to any process utilized in food production. Zymology, or fermentation science, is a field of study. The primary mechanism by which bacteria manufacture adenosine triphosphate is fermentation, which involves the anaerobic degradation of organic molecules (ATP).

Hatshy [7]

The question is incomplete as it does not have the options which are:

A.bodily humors. B.synaptic clefts. C.neurotransmitters. D.growth hormones.

Answer:

The correct answer will be option- C

Explanation:

Neurotransmitters are the chemicals released from the neurons at the synaptic junctions which helps in the transmission of the electrical impulse from one neuron to another.

The dopamine, serotonin and nor-epinephrine are the biogenic forms of neurotransmitters which are synthesized from the precursors of the amino acids. These neurotransmitters are produced in producing different functions in the body.

Thus, option- C is the correct answer.
